Abstract
Ensemble pied (22) destiné au montage de sièges pour passagers dans des véhicules de transport configuré spécialement pour absorber l'énergie, dans le cas d'un crash ou d'une autre décélération brutale avec survivants. Les pieds du siège se déforment progressivement afin d'empêcher que les charges s'exerçant au niveau de ces points de fixation au sol ne dépassent la résistance de sécurité du sol. L'ensemble pied comprend un élément de base (30) dont les extrémités avant et arrière se fixent au plancher, et un pied en V (40) dont le sommet inférieur pivote autour d'un axe passant par l'avant de l'élément de base en cas de crash avant. Le pied en V présente un élément vertical (40v) ainsi qu'un élément en diagonale (40d). Une contre-fiche (36) limitant la charge relie l'extrémité arrière de l'élément de base à une partie intermédiaire située sur l'élément en diagonale du pied en V. Une liaison de tension (38) relie la partie intermédiaire du pied en V à l'extrémité supérieure de l'élément vertical du pied en V. L'allongement de la contre-fiche limitant la charge permet le basculement des pieds vers l'avant, à une charge inertielle prédéterminée qui, si elle était sensiblement dépassée, ferait se détacher le siège du plancher. La liaison de tension s'allonge à une charge prédéterminée afin de répartir les charges à l'intérieur du siège.
